« Prev

Prerequisites

Hue service must have a network connection to an Ambari Server serving the Hue-to-Views migration tool.
Ambari Server must be enabled as a views server.
Database access rights must be granted to the Hue back-end database (mysql, oracle, and postgresql).

Supported Artifacts and Expectations

The Hue-to-Views migration tool supports migrating the following artifacts:

Hive

Saved Queries
Query History

Pig

Saved scripts
Pig Jobs

	Important
Scripts maintain the same status in the Ambari Views Framework as they had in Hue. The Hue-to-Views Migration tool does not validate scripts. Some hive queries (mysql version 0.4.0) may fail to migrate, and cause the Hue-to-Views migration to stop. The Hue-to-Views migration tool does not support HA. You must provide the current, active namenode for the target cluster regarding the Webhdfs URI for Ambari.
